OIL-CUP FOR SAWS.

SPECIFICATION forming part of Letters Patent No. 237,604, dated February 8, 1881,

Application-filed December 21, 1880.

To all whom it may concern:

Be it known that I, FRANK RoUssnAU, of Detroit, county of Vv ayne, State of Michigan, have invented an Improvement in OiHJups for Saws, of which the following is a specification.

The nature of this invention relates to certain new and useful improvements in oil-cups; and the invention consists, first, in the construction of a bifurcated delivery-nozzle; second, in the construction, arrangement, and combination of various parts for adapting said oil-cup for the purpose of lubricating sawblades, all as more fully hereinafter set forth.

In the accompanying drawings, which form a part of this specification, Figure 1 shows an ordinary haudsaw with my oil-cup attached,

. one of the plates by which the same is held in position being removed and shown separately alongside. Fig. 2 shows an ordinary handsaw to which a modified form of my oil-cu p is attached. Fig. 8 shows an ordinary gang-saw blade with my oil-cup attached. Figs. 4 and 5 are detached perspective views of the oilcups shown in Figs. 1 and 2. Fig. 5 is acrosssection on line 00 :v in Fig. 1.

In the drawings, A is the oil-reservoir, provided with the discharge-nozzle B andscrewcap The discharge-nozzle Bis partly bifurcated, as shown in the drawings forming a slit, M, large enough to allow the saw-blade to be entered.

F F are passages which lead from the oil reservoir into each bifurcation of the nozzle.

E is a stop-cock by which both passages F F can be simultaneously opened or closed.

G is a small air-Vent in the cap 0, which latter, when screwed down, will close the airvent, but by slightly unscrewing the cap the vent is opened.

If this oil-cup is recessed into the handle of an ordinary handsaw in the manner shown in Fig. 1, where the reservoir is entirely located within the handle, the bifurcated nozzle embracing the saw-blade, and the cap readily accessible for the purpose of replenishing the cup with oil, it will not in the least interfere with the free working of the saw, and it is also securely held in place by the two plates (Model D D, the oil-reservoir being just the thickness of the handle.

In Figs. 5, 2, and 3 is shown the construction and mode of attachment of a modification of my oil-cup, the two ears H H and setscrew I holding it in place in any desired position on the back of the saw-blade, while the rounding form of the reservoir will prevent its catching at obstructions. For handsaws a small portion of the wooden handle of the saw is cut away, so as to allow the ears H H to embrace the saw-blade, as shown in Fig. 2.

In practice, when it is desired to lubricate the saw-blade, the stop-cock E is opened, the cap C slightly unscrewed to allow the air access to the reservoir through the vent G, and if the saw is now held in its usual position during work-that is, obliquely, with the handle elevatedthe oil in the reservoir A will exude in drops through each bifurcation of the nozzle, cling to the saw-blade, and be distributed over the whole blade by the action of the work, the stopcock E allowing the flow of oil to be increased, diminished, or entirely stopped.

It will be seen that my oil-cup is applicable to all kinds ofreci procatin g saws that are held, during work, in an inclined or vertical position, so as to allow the oil to flow from the cup by its gravity.

What I claim as my invention is 1. An oil-cup provided with a bifurcated discharge-nozzle, each bifurcation containing a separate oil-passage, for the purpose of delivering oil simultaneously on both sides of a saw-blade, substantially in the manner described and shown.

2. As a new article of manufacture, a handsaw provided with an oil-cup, located within the handle, having a bifurcated nozzle that embraces the saw-blade, and containing passages for delivering oil for lubricating both sides of the saw-blade, substantially in the manner described.

FRANK ROUSSEAU.
